From St. John's 2nd letter he says:
"For many seducers are gone out into the world, who confess not that Jesus Christ is come in the flesh: this is a seducer and an antichrist."
Such "mini" antichrists who deny Christ and practice deceit are the likes of Justin Trudeau, or Gavin Newsome, or Ben Shapiro. I am sure you could name more historically.
Eventually, we'll get the big antichrist as per Revelation. But the word "anti" means against, so anyone who works against Christ, and uses deceit and seduction is an antichrist.
Can you tell me how you plan to go about healing people, turning water into wine, walking on water, feeding 5,000 with a basket of loaves and fishes, and rising from the dead? When you answer this, then I'll tell you how I would address those events without supernatural beliefs.
